Washington Redskins running back Alfred Morris suffered bruised ribs in his his team's 24-14 win against the Oakland Raiders on Sunday.

According to Brian McNally of the Washington Times, X-rays were negative and that there were no breaks in Morris' ribs. He left the game in the third quarter and did not return. Roy Helu took over at running back and scored an insurance touchdown in the fourth quarter to seal the victory for the Redskins.

The Redskins running back told Mark Maske of the Washington Post he bruised his ribs just after his last run.

McNally quoted Morris who said his ribs were sore but simply had to endure the pain during the game.

"It wasn't nothing that I felt like would take me out of the game. I feel like when I fell on it on that play it was kind of icing on the cake. I had to come out and be like,'Yeah, this isn't something I'm going to be able to walk off.'

"It definitely helps out to give you a little extra time to recover and get ready for the next opponent. Even though our bye week is early. Nobody likes an early bye week, but at the same time, for me, it's perfect."

Redskins head coach Mike Shanahan confirmed at the conclusion of the game that there were no fractures in Morris' ribs, although he did say they were "a little sore" and acknowledged he didn't know the real extent of the injury.

Even prior to his injury, Morris did considerable damage on the ground for Washington. He rushed for 71 yards on 16 carries before he left the game.

He is in his second NFL season. He rushed for 1,613 yards for 13 touchdowns and four fumbles in 2012, per ESPN stats.
